FEEDER ron PLANING-MACHINEs Specification of Letters Patent No. 8,702,dated February 3, 1852.

` To all whom. 'it may concern:

Be it known that I, JOHN CUMBERLAND, of the city and county `of Mobileand St-ate of Alabama, haveinvented a new and useful machine for feedingplaning-machines with boards or planks with regularity and constancy andwhich may be used for the delivery of the same after the planing hasbeen performed, and do hereby declare that the following is a full,clear, and exact description `of the construction and operation of thesame, reference being had to the annexed drawing, making a part of `thisspecification, in which- Y end elevation.

Figure l is a perspective view. Fig. 2, an

Fig. 3, a partial longitudinal section inverted, and Figs. 4, `5, and 6,partial representation.

This machine as constructed iscomposed `of two general parts.` The firstconsists of a stationary plane orbed-piece, andthe sec- 2, bycorresponding lettersA A.

rectangular plane of sufficient solidity to` ond of a movableplatformwhich is subject, for the purposes of`description, to further divisionas will appear hereinafter. The bed-piece is `represented in Figs. l,and

support `t-he superincumbent platform and its load and whose length andbreadth is to be accommodated to length and quantity of the material tobe elaborated by a planing machine. In front it projects half its widthand is notched `to receive the spring S, S, (Fig.`1,) and the standardT. Tt is furnished also with grooves Y, Y, fixed at right angles withits length on its upper surface to receive friction wheels or rollers onthe movable platform above, the direction of whose motion they areintended to control; and also `with a rack g', g, parallel with thegrooves, which receives the cogs orteeth of j the pinion on t-he handwheel or winch f,

Besides these this bed` piece contains a part of the appliances foralternate lateral motion of the movable platform. The tumbler V, Figs.1, 4, and 5 conveniently fixed bythe journal of its shaft (Figs. l, 2,and

t', 25, about the middle of A A, is furnished at either end with a clickW,`W, and thin springs X X, to keep them in proper place. On `the shaftof the tumbler `and below it is an arm U, having a slot cutlongitudinally for an adjustable pin which joins the con- Itis a` 'belowits cross head, so that when the lever is pressed forward by any force,andreleased it returns to its place by the elasticity of the spring andcommunicates a reciproeating motion to V, by the rod R, andthe arm U.The connection of` Q, R, and U, is shown by Figs. l and 4E.

H, H, are posts of a gallows frame fastened to the edges of A A, for apurpose hereafter to be named; and the wheels K, K. only suggest theportability of A. A.

The movable platform in relation to its own structure may be dividedinto two parts: a fixed platform B, B, Figs. l, 2, and

3, and an adjustable table O, O, Figsfl, and i platform B, B, and movesfreely on its ceni ter S, above Z, Z. On the opposite arms of j', j, twopins m, m, move freely in `t-he slots n', n', cut longitudinally in theratchets Z Zto receive them. At either end of the two ratchets Z Z areslots O', O, O', O, cut at right angles with the ratchets for theadmission of screws which serve the double purpo-se of fixing them tothe platform B, B, and of guiding parallely their motion when acted uponby theY lever j', j, in the direction of the length of B, B, backward orfor ward.

Attached to the Y lever j, y, are two clutches or teeth Z, X on theopposite sides by a pin working in a slot, r', and by which i also thedistances of the teeth Z and X relatively to the ratchets are regulated.The two teeth Z, and X, performan important partby losing a motion andungearing the ratchets Z, Z, which are necessary for the platform B, B,and which will be hereafter explained. v

The distance between the ratchets Z, Z, is regulated so as toaccommodate itself to the length of the tumbler V and its clicks W, W,so that when B, B, is turned over and put in its place on A, A, theywork between the ratchets in such a way that one click is always ingear. The connection of tumbler V, click W, and one 'of the ratchets Z,is sho-wn in Fig. 1.

There are four friction rollers i', z", i', i',

Figs. 3 and 2, attached (two at each end) to B, B. They are placed atright angles with it and move in the grooves Y, Y, on the bed-'piece A AFig. 1, and allow a free traverse mot-ion to the movable platform. D, D,D, D, Fig. 3, are the ends of the guide posts fastened to B, B, andappear also in Figs. 1, and 2.

f',vf', is a hand wheel (Figs. 1, 2, and 3,) at the end of B, B, on theshaft of which (6', e',) running in two boxes Q', Q', is fixed a pinionp', which works in the rack g', g', attached to the bed-piece A A, and

i enables B, B, to be moved right or left by hand.

A' A', Figs. 1, 2, and 3, is a vertical rack attached to the side andnear the end of B, B, and extends up as high as the guide posts D, D.

- C, C, is the adjustable table of the fixed platform B, B, shown inFigs. 1 and 2. This table bearsthe planks to be fed to planing machine.It has the form and size of the lower platform B, B, and rests upon it.It is pressed upward by springs as .shown by the spirals h', h', or issupported by cords P, P, which pass over the fusee J. It moves freely upand down between the guide posts D, D, which are attached to B, B, andis adjusted in the same direction by the hand rack A', A', and pinionB', B', Fig. 3.

Attached to C, C, are four vertical ratchets G, G, G, Figs. 1 and 2,with the teeth or catches turned up and fastened to four posts E, E, E,Fig. 1, and are furnished with balance clicks F, F, F, which fall ingear with the ratchets G, Gr, G, and prevent the table fromr rising up.`yThe balance clicks F, F, F, are fastened to the guide posts D, D, and

vhave on the inside, handles of sufficient weight, that by falling theyare thrown out of the teeth of the ratchets.

u', in Figs. 1, 2 and 3, is a support for the shaft C', C', and pinion12"', b, which works through the wide box o', and with the wheel el',d', forms thehand rack for moving the adjustable table up or down.

H, H, H, Figs. 1 and 2, is a gallows frame whichthe driving shaft L, L,worksV in.

N is a driving pulley on L, L, and on L, L, is a driving half wheel M,which moves or pushes the plank from the adjustable table.

The posts I, I, on the frameJ support the fusee J.

Fig. 6, represents a rack and half wheel which may be substituted forthe parallel ratchets Z, Z, for the purpose of producing thereciprocating lateral motion of the movable platform by a ratchet wheelshown by the dotted lines.

Having thus described the several parts of my invention the operationAfor the feeding of a planing machine is as follows; The planks are piledup in even and successive tiers on the adjustable table C, C', Fig. 1,which brings it down to the platform B, B. vThe handles of the balanceclicks will rest` upon the t-iers of plank which being pressed up by thesprings h', h', or supported by the cord P, P, and weight O, over thefusee J, or the hand rack A', A', will be kept in gear with the verticalracks Gr, G, G, and hold C, C, in itsplace. The uppermost planks on the.several tiers on the table C, C, are now a little lower than plank ofthe first tier is forced forward byv t-he driving half wheel and carriesthe lever Q, forward with it, which as soon as the plank is over,returns to its place by the energy of the spring S, S, which pressesagainst it. The lever Q, acting through the rod R, and arm U,communicates its motion to the tumbler V, which hasA one of its clicksW, in gear with one of the teeth .of the parallel ratchets Z, and movesthe movable platform laterally so as to bring the next'tier of planks tothe place just occupied bythe first. The first plank of the second tieris then removed with like action of the feeding machine and so on tillthev last tier of planks is reached.v Now it is required that two planksmust be removed successively before the movable platform begins toreturn in the opposite direction. When the rst plank on the last tier isremoved the return of the lever Q, has no longer acted on the ratchet Zbut on the adjusted tooth Z on the' Y lever j', 7", and has turned the Ylever on its center s', without any other action on the parallelratchets Z Z than throwing` the ratchet out of gear which brought themovable platform to its present position and bringing the other ratchetnow into connection with the opposite lclick of the tumbler V. Theplatform therefore loses a motion and when the second plank of the lasttier is removed the lever Q will then advance it one degree in theopposite direction as `the click will act on the other ratchet. Thelever Q will now continue to move the platform until the rst tier "isagain reached when coming into play Withthe tooth X', on the other sideof B, B, another motion Will be again lost and thus all the planks Willbe taken away in succession as the movable platfo-rm traverses thebed-piece from side to side. rlhe balance clicksadjust themselves. Thehandles rest upon the planks and when they are moved from under theclicks the handles fall and let go` a `catch ortooth in the rack Gr, G,G, and as the planks are forced up by the spring or Weights the clicksare again brought into gear with the ratchets, so that the balanceclicks permit the movable platform to rise the thickness of a plank asoften as top layers of the tiers are shoved off.

lhen the machine above described is used for the delivery of boards froma planing machine after they are dressed its parts and structure are thesame as above shown eX- cepting that the teeth of the ratchets Z, Z, andthe clicks XV, WV, on the tumbler V are reversed, and the lever Q, andthe springs S, S, change places in the notch in A, A, so that the latterpresses the former forward instead of back as above described. The

act-ion of the movable platform will then be accommodated to thereception of the dressed material as it was before to the purpose offeeding the planks to the plane.

What I claim and desire to secure by Letters Patent is- My abovedescribed combination of a bedpiece, Wit-h the spring, lever, connectingrod, arm, tumbler and click; and its grooves, guides and rack, with amovable platform With the `adjusting levers, and ratchets for theproduction of a lateral traverse and lost motion, with its adjustabletable, adjusted by springs, Weights, screws or other known mea-ns; Withits hand Wheels, rollers, vertical ratchets and balance clicks; and of aframe with its pulley and half Wheel for the purpose of delivering orreceiving material thereon, the Whole being constructed, combined andoperating, as above set forth and described and for the purposesmentioned.
